In this paper, we first discussed the nature of
routine and creative action, and that
control decisions should be made in cortical planning modules.
We then discussed the basal ganglia loops and
mapped these onto our system-level brain model.
We then discussed how initiation, monitoring
and control of routine action could be
achieved by providing the planning module with
the ability to monitor a stream of routine action descriptions,
and to allow this to flow or else to instead make
creative actions.
We finally outlined in a neural level of description
how different cortical layers and the thalamus might be
involved in routinized mental action.
